odoo.connect(function (err) {
if (err) { return console.log('odoo.connect handle error: ',err); }
});
} catch (err) {
console.log('odoo.connect error: ',err);

It can't be handled with try{} catch{} construction too
But wrapping response = JSON.parse(response); into try{} catch{} can solve this problem:
try {
response = JSON.parse(response);
} catch (err) {
return cb(err, null);
}in res.on('end', ...) will handle the error instead of throwing it:
odoo.connect handle error: [SyntaxError: Unexpected token <]
